you can make very simple adjustments by making a carpool which is the easiest and the best solution that is needed in the hour.
Carpools are only useful in a city. I have a job where my nearest coworker is 100 miles away. There is no way I can carpool. In Urban and small town areas people just live too far apart to be able to carpool effectively.
The best way to save fuel is to properly service all of your vehicles. Little things like tire pressures, air filters, and proper tune ups conserve a lot of fuel.
